1. The problem statement, all variables and given/known data
help me out. I want to find the integral of 1/(cosx1). I first multiplied the function by cosx+1/cosx+1. then i ended up with the integral of (cosx+1)/(sinx)^2 leading to integral of cosx/(sinx)^2 plus integral of 1/(sinx)^2. the integral of 1/(sinx)^2 i believe is just cotx. the integral of cosx/(sinx)^2 i think is (integral of cotx*cscx) 2. Relevant equations integral of 1/(cosx1)

What's your question? I don't see anything wrong in what you've described. You can check any antiderivative you get by taking its derivative. If you get back to the integrand, you're good.
